<p>PURPOSE:To prevent deformation of a concatenated body for lining the internal surface of an existing pipe by forming a tube inserted into the concatenated body held inside the existing pipe into a rigid body to support the concatenated body, filling the gap between the internal surface and the wall of the concatenated body with filler material and allowing the filler material to cure, thereafter removing the tube. CONSTITUTION:A concatenated body 2 consisting of short pipes 5 is inserted into an existing pipe 1 such as Hume pipe, etc. A tube 3 is insert ed into the concatenated body 2, and air or water is fed into the tube 3 to expand and form the tube into a rigid body. The wall of the concatenated body 2 is backed up from the inside by the rigid tube 3. After that, a fluid filler material is injected into a gap formed between the existins pipe 1 and the concatenated body 2, and the tube 3 is removed after the filler material has cured. Since the cured filler material has a self-supporting property, deformation of the concatenated body due to the weight of the filler material can be prevented.</p> |
